The present invention relates to a light assembly with separable threaded connector, and more particularly, to a light assembly that includes a body, a connector and an illumination member which is threadedly connected to the connector.
The conventional light assembly known to applicant is disclosed in U.S. Pat. No. 7,144,135 and comprises a shell; an optical reflector disposed at least partially within the shell, wherein a space is formed between the optical reflector and the shell; at least one light emitting diode disposed within the optical reflector; a heat sink disposed at least partially within the shell, the light emitting diode being mounted to the heat sink; a motor and a fan in flow communication with the space, the fan being configured to move air over the heat sink and through the space; and a screw type electrical contact base coupled to the shell.
However, the base and the shell are integrally formed as an one piece when the light assembly is manufactured, so that the whole light assembly occupies a significant space and a larger packing material is needed to pack the light assembly. Besides, the empty room in the box for receiving the light assembly requires a lot of cushion material to fill the empty room. The larger boxes also increase higher transportation cost.
The base is integrally connected with the shell, so that once the base is damaged, the shell is discarded with the base. The shell is made of metal which is expensive, and this wastes a lot expensive material.
The present invention intends to provide a light assembly which saves the packing material. The illumination member and the light assembly are packed individually so as to reduce the storage and transportation space required.
The present invention relates to a light assembly which comprises a body having a first opening in the first end thereof, and a second opening is located in the second end of the body. The first opening is larger than the second opening. The body has a recessed area defined in the second end of the body. The recessed area is a circular recess and has a first flange. Multiple first holes are defined through the first flange. The body has a first outer periphery on the second end of the body. The body has a second outer periphery on the first end of the body.
A connector is received in the recessed area and contacts the first flange. The connector is a ring-shaped member and has multiple third holes which are located correspond to the first holes. The number of the third holes is the same as that of the first holes. The connector has a first threaded portion defined in the inner periphery thereof.
Multiple first threaded members extend through the first holes and the third holes, and are connected to multiple second threaded members so as to connect the connector to the body. The first threaded members have outer threads and the second threaded members have inner threads.
An illumination member has a second threaded portion which is threadedly connected to the first threaded portion so as to connect the illumination member with the connector. The second threaded portion has outer threads which are threadedly moveable relative to the first threaded portion to adjust the relative position between the illumination member and the body to adjust focus of the light assembly. A base is connected to one end of the illumination member and protrudes beyond the body.
The illumination member can be threadedly separated from the connector so that the rest of the parts of the light assembly and the illumination member are individually packed to reduce the storage space needed, and the transportation cost.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
